Description
Technical field
The invention belongs to the technical field of pressure reducing valve more particularly to a kind of protecting against shock three-way pressure reducing valves.
Background technique
Pressure reducing valve is inlet pressure to be reduced to the outlet pressure of a certain needs, and by the energy of medium itself by adjusting
Amount, makes outlet pressure automatically keep stable valve.From the viewpoint of hydrodynamics, pressure reducing valve is that a local resistance can become
The restricting element of change changes the kinetic energy of flow velocity and fluid, causes the different pressure losses that is, by change orifice size, from
And achieve the purpose that decompression.Then by the adjusting of control and regulating system, the fluctuation of downstream pressure is made to balance each other with spring force,
Keep constant downstream pressure in certain error range.The pressure reducing valve of the prior art, such as Patent No. CN101625043A,
The patent of invention of entitled high-pressure pressure-reducing valve is provided with spool and valve seat, and valve seat is equipped with throttle orifice, and spool is equipped with and throttling
The throttling conical surface of the lower aperture movable sealing cooperation in hole, when outlet pressure reaches setting pressure, the throttling conical surface of spool is closed
Lower aperture, when outlet pressure variation is very fast, the movement speed of spool too fast envoy's flow cone face and lower aperture rapid closing, impact
It is very big, cause the service life of spool and valve seat too short；In addition, when the throttling conical surface of spool has been switched off lower aperture, if
Outlet pressure continues to increase, and has lost pressure adjustment effect, has not had safety protection function, needs to increase on pipeline
Additional overflow valve causes piping connection complicated, at high cost.
